I have an app which has iOS 6.1 as the minimum deployment target. In my project I'm using a couple of 3rd party libraries. When I try to run my app using Xcode 6.1.1, on an iOS 6.1.3 device, I'm getting this error and the app cannot continue running:

dyld: Symbol not found: _AVAudioSessionMediaServicesWereLostNotification Referenced from: /var/mobile/Applications/8CCB531B-1749-4484-8B6B-AF6221CB409D/ProductName.app/ProductName Expected in: /System/Library/Frameworks/AVFoundation.framework/AVFoundation in /var/mobile/Applications/8CCB531B-1749-4484-8B6B-AF6221CB409D/ProductName.app/ProductName

OK, AVAudioSessionMediaServicesWereLostNotification is available after iOS 7.0 and that's the problem. What I need to know is which 3rd party library of mine is causing this error. Do you know how I can track this error message and learn which library is responsible of this?
